The present study examined the effects of dry grinding, using ball‐milling, on structure reference well‐crystallized (KGa‐1) and poorly crystallized (KGa‐2) kaolinite powders from Georgia. Grinding produced a strong structural alteration, mainly along c axis, resulting in disorder total degradation crystal formation an amorphous product. surface area increased with grinding time, KGa‐2 (maximum value 50.27 m 2 /g), result associated particle‐size reduction. These particles became more...
The employment of synchrotron techniques complemented by conventional laboratory systems has allowed us to deepen and improve our knowledge Roman wall painting procedures. palette identified in paintings from Pompeii Herculaneum the second century bc includes goethite, hematite, cinnabar, glauconite, Egyptian blue, other components such as calcite aragonite. Proof use organic binders is provided FTIR PY–GC/MS. Therefore, possibility ‘a secco’ cannot be ruled out. Pigments are usually found...
This Letter reports on the first cross-section measurements for Sr94(α,n)Zr97 and Kr86(α,n)Sr89 reactions. In particular, our measurement of is weak r-process reaction cross section obtained using a radioactive ion beam. experiment was enabled by use novel solid helium targets, comprised silicon thin films with high incorporation via sputtering technique. Yield were performed at center-of-mass energies 10.4 9.0 MeV reaction, 9.9 Sr94(α,n)Zr97, extending into respective Gamow energy windows...
<title>Abstract</title> Sputtering of cobalt, silicon and zirconium in a helium magnetron discharge (MS) is reported as bottom-up procedure to obtain He-charged films (i.e. <sup>4</sup>He <sup>3</sup>He filled nanopores encapsulated the matrix material). Composition microstructural analyses are presented from ion beam analysis (IBA) scanning transmission electron microscopies (SEM TEM). Helium desorption was investigated by IBA dedicated chamber for “in situ” thermal evolution vacuum. The...
The methodology termed scanning transmission electron microscopy in (STEM-in-SEM) has been used this work to study the uptake of citrate stabilized gold nanoparticles (AuNPs) (average particle sizes 23.5 ± 4.0 nm) into tissue samples upon vitro exposure dissected gills Ruditapes philippinarum marine bivalve nanoparticle suspensions. STEM-in-SEM optimized for achieving optimum resolution under SEM low voltage operating conditions (20-30 kV). Based on microscope assessments and testing...
A detailed electronic and microstructural characterization is reported for the LiBH4–MgH2 reactive hydride composite system with without titanium isopropoxide as additive. Surface by x-ray photoelectron spectroscopy combined to a morphological study scanning electron microscopy well elemental map composition analysis energy dispersive emission are presented in this paper first time all sorption steps. Although reactions not complete at surface due unavoidable superficial oxidation, it has...
